Pneumatic control valve self-reliance type differential pressure bypass control pneumatic valve application

normally closed type differential pressure bypass control pneumatic valve used for fuel, gas, heat supply and return pipe, central air conditioning, between points, Siamese as a measuring flow, secondary side bypass installation of variable flow system, which can effectively protect the fuel, gas units will not damage due to flow high temperature caused by too small, is effective in protecting the chiller caused by traffic is too small and partial freezing damage.
normally open type differential pressure bypass control pneumatic valve used for large height difference and the heat source in the central heating system of high area, according to the difference in height setting when using differential pressure of the pneumatic valve, and in the low return pipe position vacuum pump installation, check the pneumatic valve, pneumatic valve regulating of backwater pressure-relief devices, by adjusting the pneumatic valve to regulate and set back to the pipe pressure and this can ensure high area users won't appear empty phenomenon, but also protect the equipment will not damaged by high pressure low area.
